DESCRIZIONE DESCRIPTION

DISEGNO PRINCIPALE (FIG.l - FIG.2) MAIN DRAWING (FIG.l - FIG.2)

Fig. 1 Sezione dell’attrezzo di supporto con MONCONE (01 ). Fig. 1 Section of the support tool with ABUTMENT (01).

BUSSOLA PORTAMONCONE (02) con relativa BOCCOLA FILETTATA (02-1). COMPASS HOLDER (02) with relative THREADED BUSH (02-1).

VITE (03) con estremità conica per il bloccaggio assiale del moncone. Fig.2 Vista in pianta dell’ attrezzo. SCREW (03) with conical end for axial locking of the abutment. Fig.2 Plan view of the tool.

Il sistema di bussola con moncone è composto da un perno moncone (01) su cui vi sono sul gambo superiore delle scanalature atte a trattenere Timpronta del dente, ottenuta colando un materiale gessoso o di resina acrilica. The bushing system with abutment is composed of a pin abutment (01) on which there are grooves on the upper shank to hold the tooth impression, obtained by pouring a gypsum or acrylic resin material.

Il gambo inferiore del perno moncone, ha sezione poligonale in modo che, inserendosi nella sede di uguale sezione e dimensione della bussola (02), viene a collocarsi sempre nella stessa posizione radiale. La bussola portamoncone (02) ha forma e dimensioni ridotte per potersi posizionare con il relativo moncone dell’ impronta di ognuno dei 16 denti, componenti l’arcata dentaria superiore o collocarsi nell’ impronta di ognuno dei 16 denti componenti l’arcata dentaria inferiore. The lower shank of the post-abutment has a polygonal section so that, by inserting itself into the seat of the same section and dimension of the bush (02), it always comes to place itself in the same radial position. The abutment holder bush (02) has a reduced shape and size to be able to be positioned with the relative abutment of the impression of each of the 16 teeth, making up the upper dental arch or to be placed in the impression of each of the 16 teeth making up the lower dental arch.

La bussola ha n.2 scanalature radiali che la incastrano nella colata formante la base dell’ impronta, impedendo così di sfilarsi. The bush has 2 radial grooves that fit it into the casting forming the base of the impression, thus preventing it from slipping off.

La bussola ha come sopra dett, una sede verticale a sezione poligonale dove si inserisce il gambo inferiore del moncone impedendone la rotazione e ne fissa una posizione radiale fìssa e sempre uguale. Inoltre nella bussola vi è fusa una boccola filettata (02- 1) in cui va ad avvitarsi la vite (03). Quest’ultima ha la parte finale del gambo filettato conico in modo che la vite avvitandosi nella boccola filettata la parte conica si inserisce nella sede conica del gambo del moncone fissandolo assialmente in una posizione sempre uguale che dà riferimento e precisione al sistema. As stated above, the bush has a vertical seat with a polygonal section where the lower shank of the abutment is inserted, preventing it from rotating and fixing a fixed radial position that is always the same. Furthermore, a threaded bush (02-1) is cast in the bush into which the screw (03) is screwed. The latter has the final part of the tapered threaded shank so that the screw, by screwing into the threaded bushing, the conical part fits into the conical seat of the stump shank, fixing it axially in an always the same position that gives reference and precision to the system.

La testa della vite fuoriesce dalla colata della base per essere visibile e accessibile e potersi avvitare o svitare per bloccare o sboccare il gambo del moncone per poterlo rimuovere dalla bussola, anche rimuovendo varie volte il manufatto dalla bussola con il relativo moncone (01), operazione necessaria per le fasi successive del lavoro da eseguire. The head of the screw protrudes from the casting of the base to be visible and accessible and to be screwed or unscrewed to lock or unscrew the shank of the abutment to be able to remove it from the bush, even by removing the product from the bush with the relative abutment several times (01). necessary for the subsequent phases of the work to be performed.

Questi ultimi, una volta rimontati nella bussola, vanno a riposizionarsi e bloccarsi con precisione sempre come erano ad inizio lavorazione, conferendo la massima precisione del manufatto permettendo di raggiungere Γ obbiettivo di avere un ottimo supporto tecnico dì lavorazione. The latter, once reassembled in the bush, go to reposition and lock with precision, always as they were at the beginning of the work, giving maximum precision to the product allowing to reach the goal of having an excellent technical support for processing.

Claims

CLAIMS 1) Both the constructive form of the bush (02) and its construction in any material (metal, resin, plastic, etc.) which ensures its stability and shape over time are claimed.

2) The constructive form of the pin abutment (01) with lower shank with anti-rotation polygonal section and conical groove for axial fixing is claimed.

3) The constructive form of the metal screw (03) with Γ conical end, for fastening the abutment pin (01) in the sleeve (02), is claimed.

4) The axial locking of the post abutment is claimed, both through the screw with conical end, and through all other types of locking.

5) Both the dimensions and the Γ assembly between them and individually of the three pieces (bush, pin abutment, axial locking screw) and the idea that determines the system for the precision of the development of the dental impression are claimed.
